This is a domestically produced semi-dry wetsuit meticulously crafted with attention to sewing, specifications, and details. The sponge is based on the highest grade DT sponge from National Rubber Co., Ltd., Japan's largest manufacturer, which is also used by famous overseas and domestic brands. For the outer jersey on the underarm gussets, crotch gussets, buttocks, and back of the knees, we use super-stretch jersey (relaxation jersey) jointly developed with a renowned Japanese textile company, offering excellent texture and elasticity. The suit's brushed lining uses one of Japan's leading highest-grade brushed materials, excelling in quick-drying, mobility, heat retention, and cost performance. For enhanced comfort during surfing, this semi-dry suit comes standard with an inner neck. By equipping the inner neck, we prevent water intrusion and improve heat retention compared to traditional designs. We are committed to crafting this suit with meticulous attention to detail to ensure customer satisfaction. #surfing #wetsuit #semidrysuit #fullsuit #longjohn #backzip #nonzip #chestzip #longchestop #airflameboost L Size Details 1 Height: 176 2 Weight: 67 3 Neck Circumference: 37 4 Shoulder Width: 45 5 Upper Chest Circumference: 98 6 Waist Circumference: 78 7 Hip Circumference: 92 8 Back Length: 68 9 Sleeve Length: 77 10 Upper Arm Circumference: 29 11 Elbow Circumference: 25 12 Forearm Circumference: 27 13 Wrist Circumference: 16.5 14 Inseam: 72 15 Below Knee Circumference: 33 16 Calf Circumference: 36 17 Ankle Circumference: 22 (Notes) 1.
